We look at the division of 18227639 by 869 
We want to divide 18227639 by 869.

Advancing to step 1:
The number 869 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 869

Going ahead to step 2:
18 divided by 869 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Append the next digit (2) from the dividend to 18 and continue with: 182 / 869

Moving on to step 3:
869 goes into 182 0 times with a remainder of 182.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 182 after subtracting 0 from 182.
Include the next digit (2) from the dividend after 182, then repeat: 1822 / 869

On to step 4:
When dividing 1822 by 869, we get 2 with a remainder of 84.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 1738 from 1822 and we're left with 84.
Bring next digit (7) of the dividend behind the 84 and repeat the process: 847 / 869

On to step 5:
If we divide 847 by 869, we get 0 and a remainder of 847.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 847 leaves us with 847.
Grab the next digit (6) from the dividend, add it to 847, then carry on: 8476 / 869

Step 6:
When dividing 8476 by 869, we get 9 with a remainder of 655.
Write down 9 as next digit of the result. 
Result so far: 209.0
If we subtract 7821 from 8476, we get 655.
Grab the next digit (3) from the dividend, add it to 655, then carry on: 6553 / 869

Moving on to step 7:
869 goes into 6553 7 times with a remainder of 470.
Put 7 as the next digit of the answer. 
Result so far: 2097.0
If we subtract 6083 from 6553, we get 470.
Include the next digit (9) from the dividend after 470, then repeat: 4709 / 869

Moving on to step 8:
If we divide 4709 by 869, we get 5 and a remainder of 364.
Put 5 as the next digit of the answer. 
Result so far: 20975.0
If we take 4345 away from 4709, we end up with 364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Advancing to step 9:
3640 divided by 869 is 4 with a remainder of 164.
The number 4 becomes the next digit in our result. 
Result so far: 20975.4
Subtract 3476 from 3640 to get 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Step 10:
If we divide 1640 by 869, we get 1 and a remainder of 771.
The next digit of our result is 1. 
Result so far: 20975.41
Subtract 869 from 1640 to get 771.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7710, and continue the process.

Advancing to step 11:
The number 869 fits into 7710 8 times, leaving a remainder of 758.
The number 8 becomes the next digit in our result. 
Result so far: 20975.418
If we subtract 6952 from 7710, we get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

Moving on to step 12:
The number 869 fits into 7580 8 times, leaving a remainder of 628.
Use 8 as the next digit of our solution. 
Result so far: 20975.4188
If we subtract 6952 from 7580, we get 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

In conclusion, the division gives 20975.4188 with a balance of 0.00628.
